An accelerated flow is in the ePVA with no corresponding software connection.
ePVA can continuously send a packet. This might eventually result in a network outage.
-- FastL4. -- ePVA. -- The other conditions under which this occurs are not well defined.
Disable HW acceleration.
There are now no unknown accelerated flows.
The default behavior is to ignore unknown HW accelerated flows (connections). This change will proactively evict unknown HW accelerated flows from the HW (ePVA).
